While still years away from possibly ever being completed or executed, NASA's Innovative Advanced Concepts department recently granted $100,000 in funding to a dozen exotic new projects. Amongst the recipients are a nanosatellite which would capture space debris and asteroids (seen here) as well as a new imaging system that would allow for probes to explore caves on the moon. Indicative of NASA's strong interest in Saturn's moon Titan, two unique concepts aimed at exploring the mysterious world were awarded funding: a balloon and a submarine.
